| Doc Text: |
mcelog is unable to obtain MCE data from paravirtualized Xen guests on
a system. Previously, each time that mcelog tried and failed to obtain
this data, it would generate an error report -- by default, once per
hour. These error reports could mislead users to think that there was a
problem with their system. Now, mcelog does not generate error reports
when it cannot obtain MCE data from paravirtualized Xen guests, and
therefore avoids any potential confusion.

<riel> prarit: probably easiest from the shell script that's invoked by cron * dkl (~dkl.redhat.com) has joined #devel <prarit> riel: yup. Is there something I can look for in /proc or /sys to identify a PV domU? <riel> (1) /proc/xen exists and (2) the contents of /sys/hypervisor/uuid are not all zeroes (dom0 has all zeroes there) <riel> for some reason I do not know, /proc/xen/privcmd now shows up in domU too :) <prarit> riel: Thanks :) .... looking at a freshly installed domU now. Created attachment 354485 [details]
RHEL5 mcelog.cron fix
Created attachment 354487 [details]
RHEL5 new spec file
Bare-metal, domU, and dom0 tests all successful with the above fix. P. Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: mcelog is unable to obtain MCE data from paravirtualized Xen guests on a system. Previously, each time that mcelog tried and failed to obtain this data, it would generate an error report -- by default, once per hour. These error reports could mislead users to think that there was a problem with their system. Now, mcelog does not generate error reports when it cannot obtain MCE data from paravirtualized Xen guests, and therefore avoids any potential confusion.
